Manual of Labor Units (MLU), 2017-2018 Edition CD

An estimate is only as good as the information it is based on, and the NECA Manual of Labor Units (MLU) has been the estimating resource of choice for electrical contractors since 1923. The MLU provides an experience-based reference for estimating the electrical construction labor required to install typical electrical and communications systems.

This edition features a complete reorganization to better assist electrical contractors with their estimating processes. All labor units within the manual now correspond with the Construction Specification Institute’s MasterFormat, 2016 Edition.

Some of the features of the MLU CD are:

  • PDF of the entire book
  • The ability to move from table to table and section to section
  • A factoring chart for determining the proper labor column to use for a project
  • The ability to customize the factoring of labor indicated in the tables for individual company productivity
  • A heat and humidity factor calculator
  • A calculator for the time extension of a project beyond normal project duration
  • Conductor fill and conduit size calculator
  • A calculator for electrical formulas, such as Ohms Law
  • A calculator for the conversion of units of measurement such as metric to standard
  • The ability to export labor units to Excel files

This CD will only work with Windows operating systems.
